Constructor & Destructor Documentation

◆ CScale()

DirectGraphicalModels::fex::CScale::CScale ( const Mat & img )

inline

Constructor.

Parameters

img	Input image of type CV_8UC1 or CV_8UC3.

Member Function Documentation

◆ get() [1/2]

virtual Mat DirectGraphicalModels::fex::CScale::get ( void ) const

inlinevirtual

Extracts and returns the required feature.

Returns: The feature image.

Implements DirectGraphicalModels::fex::ILocalFeatureExtractor.

Definition at line 26 of file Scale.h.

Here is the caller graph for this function:

◆ get() [2/2]

Mat DirectGraphicalModels::fex::CScale::get	(	const Mat &	img,
		SqNeighbourhood	nbhd = `sqNeighbourhood(5)`
	)

static

Extracts the scale feature.

For each pixel of the source image this function calculates the mean value within the pixel's neighbourhood nbhd. Using different neighbourhood radii, it alows for different scale representations of the features.

Parameters

img	Input image of type CV_8Uxx with arbitrary number of channels.
nbhd	Neighborhood around the pixel, where the mean is estimated. (Ref. SqNeighbourhood).

Returns: The scale feature image of the same type as input image.
